Send me the "corrupt" client.wyc to wyatt@wyday.com

Hi,

Corrupted file sent already please do the needful as soon as possible.

Your immidiate response is highly appreciated.

The file isn't corrupt.

This error means the client.wyc file can't be found:

The client data file (client.wyc) failed to open.

Full details:

Could not find file 'C:\Applicationpath\iuclient.iuc'.

Which usually means you renamed the client.wyc file or moved it outside of the folder wyUpdate.exe.

Thanks for your response..

After I change the name to client.wyc , wyUpdate.exe is working fine, no exception is thrown (thats a big relief . my sincere thanks for you), bu the wyUpdate.exe icon has been chagned to default brown one. Before we modified to have customized image.. For this do i need to modify the code again?

Thanks,Banu

You're talking about a custom version of wyUpdate? If so, then yes, you need to keep up with the latest wyUpdate source code: How to make a custom version of wyUpdate.

Hi Wyatt,

We have been using wyUpdate for a long time. Everthing was working ok, but since 2 weeks we are having problems with the updates, we have the error message described in this thread:

Could not find file 'C:\Applicationpath\iuclient.iuc'. I don't now what have changed, is beacause and update of wyBuild, Windows 10, i don't know even old installers build 1 year ago that have work in the past today they don't work we have this message.

Do you have any hint or information that can explain this?

Best RegardsNorman Acosta

Hey Norman,The error you're getting is because the client.wyc file no longer exists.The most likely cause is that your update is not correctly designed. Namely, you're accidentally deleting the file. See how wyBuild compares versions of your app and decides what files to change, add as new, and delete: https://wyday.com/wybuild/help/faq.php#how-it-works

Let me know if youhave any other questions.

Also,this topic is really unrelated to your question (differentissues).
